(or. l5617) 18 Claims.

My invention relates to a-Venetian blind, and more particularly to a Venetian blind having the usual rout openings through which cord or .pther supporting means extends, for the support of the bottom member of the blind.

The principal object of the invention is to provide such a Venetian blind that may be closed, despite the supporting cord means, to a point where the spaces between the slats are substantially closed, thus substantially preventing the penetration of light.

Heretofore, in blinds of this character, the supporting cord means has prevented the slats from coming together sufliciently close to shut out light; in fact, the cord means holds the slats apart, preventing closure of the blind.

In Venetian blinds now in use, it is difficult,

if not impossible, to raise and lower the blinds,

when the slats are in their closed position. It is an object of my invention to provide means whereby the blind may be raised or lowered even though the slats are in their closed position.

Still another object of the invention is to provide means whereby short, standard lengths'of Venetian blind slats may be used, irrespective of the over-all length desired for a Window.

Other objects of the present invention are to provide such a blind that is positive in operation, easily installed, economical of manufacture, and relatively simple.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawings merely show and the following description merely describes embodiments of the present invention, which are given by way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

Fig. 11 is a section taken on the line ll-l| of Fig. 10.

Fig. 12 is a perspective view of a connecting member comprised in the latter embodiment.

Referring more in detail to the drawings, the reference numeral 6 generally designates the foot block of a Venetian blind, which is supported by means of cords I and 8. Rear and front straps 9 and I0, respectively, are fastened to the lower side of the block. 6 by suitable tack means l2. The straps'9 and III and the cords I and 8 are supported from the head (not shown) of the Venetian blind. The head of course includes any conventional adjusting means for the straps and cords.

Sewed to the opposing faces of the straps 9 and l 0 are cross tapes I 3, which supportVenetian blind slats I4, the slats l4 having elongated rout openings l5 therein for the cords 1 and 8.

The slats M are preferably resilient metal that is adapted to be coiled upon itself and when released to resume the shape shown in Fig. 1. Alined with the ends of the rout openings IS,

the slats l4 have beads I 6 and I1 bent in opposite directions with regard to each face of the slats. The slats have similar beads, in order that they may provide complementary grooves for the cords when the slats are moved to a closed position.

In the modified construction shown in Figs. 7 to 9, similar straps 9 and Ill and cross tapes [3 are utilized. The slats 20, however, are preferably substantially Sshape in cross section and in end elevation, as best shown in Fig. 9. Grooves 2| and 22 are likewise arranged at opposite sides of a rout opening 23 for the cord 1. The grooves 2| and 22 form bosses on the backs of the curves of the S shape of each slat. The grooves 2| and 22 are complementary, in order to receive the cord 1 therebetween.

In the modified construction shown in the Figs. 10 to 12, sections 24 and 25 of a Venetian blind slat are shown .as being held in alignment by a connecting member 26, which comprises a face plate 21 provided with a r'out opening 28 for receiving the .cord 1. Ribs 29 and '30, at opposite sides of the rout opening 28, project in opposite directionswith respect to the cord 1 and provide incline grooves for engaging the cord. The

grooves zend' 30 are inclined sufficiently to permit the slats to overlap at an angle, as shown in Fig. 11, while the cord 1 remains vertical.

The face plate 21 has flanges 3| and 32 bent downwardly and upwardly toward each other. The flanges 3| and 32 form gripping fingers for the Venetian slat sections 24 and 25. These Venetian slat sections may be of either wood or metal. Moreover, the ribs 29 and 30 provide abutments for the ends of the slat sections 24 and 25.

In the use of my invention, it is believed clear that all forms of the blind are operated in the usual manner of Venetian blinds. The angular arrangement of the slats and foot block 6 is adjusted by means of the tapes 9 and I0. Moreover, the blind may be raised by drawing upward the cords I and B.

When the blind is movedto a closed position, by moving the tapes 9 downward, as indicated by the arrow B, and by moving the tapes it! upward, as indicated by the arrow C, the slats are moved to a position in which they touch each other. In this position the only light that will pass through will be'through the complementary grooves l6 and [1, which is slight, if any. Otherwise, the slats will substantially close out light between the slats. When the blind is moved to the closed position, by moving the straps in the directions of the arrows B and C, the raised portions of the beads in each of the forms will project outwardly. This permits a very close association of the edge of one slat with the side of the next slatwithout interference by the supporting cord.

The blind shown in Figs. 2 and is moved to its open position by moving the straps 9 and ID in the directions of the arrows D and E. The blind shown in Figs. 8 and 9 is moved to its open position by moving the straps 9 and ID in the directions of the arrows F and G.

In the use of the form shown in Figs. 10 to 12, the slat sections are slid'longitudinally under the gripping fingers 3| and 32 until their ends substantially abut the ribs 29 and 30. It is believed clear that the ribs 29 and 30 on adjacent slat connecting members will form complementary grooves for receiving the cord 1., so that the slats may overlap and still the supporting cords will not keep the slats apart.

It is believed clear that the slot sections 24 the slots having means offset beyond the faces. forming transverse grooves between the apertures and the sides of the slats, and the grooves on adjacent slats being complementary to each other for receiving the cord means, when the blind is moved to a closed position.

and 25 may be of short, standard lengths, but

that such sections may be connected together to obtain any desired over-all length. The cost of short, standard sections is considerably less than the same amount of board feet in long slats. This applies particularly to wooden Venetian blind slats.

While I have illustrated and described what I now regard as the preferred embodiment of my inv ntion, the construction is, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of construction illustrated and described, but desire to avail myself of all modifications which may fall within the scope of the appended claims. a
